DUMPlNG-CAR.

{SPECIFICATION forming part of Letters Patent No. 476,780, dated June14, 1892.

Application filed January 9, 1 89 2.

To all whom it may concern:

Be it known that I, CYRUS WV. BRIDEGUM, of North Hector, in the countyof Schuyler, in the State of New York, haveinvented new and usefulImprovements in Dumping-Cars, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

The object of this invention is to provide a dumping-car which shall bemore convenient and more efficient in its operation; and to that end theinvention consists in the improved construction and combination ofparts, as hereinafter fully described, and set forth in the claims.

In the annexed drawings, Figure 1 is a side elevation of adumping-carembodying my invention. Fig. 2 is a horizontal section taken on line 00a: in Fig. 1. Fig. 3 is an end view of the said car. Fig. 4 is avertical transverse section on line y y, Fig. 1. Fig. 5 is a detachedplan view of the manipulating end of the dumping-lever, and Fig. 6 is adetail view of the pivot of the gate.

Similar letters of reference indicate corresponding parts.

A represents the truck, which may be of any suit-able construct-ion, andin fact it may constitute the frame and running-gear of a cart.

1) denotes the body or box in which the load is carried. This body Iprovide with a pivotal support 0 on the truck, which support Ipreferably form of an elongated plate pivoted at one edge to suitablebearings O C, firmly secured to the top of the truck a short distancefrom the longitudinal central line toward the dumping side thereof. Tothe opposite or upper edge of said plate I hinge the body B, also at ashort distance from the longitudinal central line toward the dumpingside of the car, as shown in Fig. 3 of the drawlugs.

To support the body B in a horizontal position, I firmly secure to thetruck farthest from the dumping side of the body the props D D, unitedat the top by horizontal stringers, as shown in Fig. 1 of the drawings.Said side support is firmly sustained in its upright position by meansof braces D D, extending from the top thereof toward the central portionof the truck, so as to enable the support Serial No. 417/144. (Nomodel.)

to resist the lateral strain incident to the dragging of the body towardthe opposite side of the truck during the first part of its movement toa dumping position. The body is further supported in its horizontalposition by the lever L, fulcrumed on the truck and formed at one endwith an oblique upwardlyextending arm' L, upon which the dumping side ofthe body rests when placed in a horizontal position, said lever beingconfined in said position by suitable locking devices connected to thetruck and lever. To utilize this lever for dumping the body and forrestoring it to its horizontal position, I firmly attach said levertransversely to the pivoted support 0, as best seen in Fig. 4 of thedrawings, and provide the manipulating end of the lever with alongitudinally-adjustable extension L", which I preferably form with abifurca tion e, the two arms of which embrace opposite sides of thelever and are slotted longitudinally and terminated with perforated ears6 e. To opposite sides of the lever L, I attach longitudinal guide-rodsd d, terminating with offsets which enter the sides of the lever andsustain the guide-rods short distances from the lever. Said guide-rodspass through the ears e e, and the ends or offsets of the guiderodsadjacent'to the end of the lever L pass through the longitudinal slotsin the arms of the bifurcation of the extension L. Said extension canthus be drawn out to afford greater purchase of the lever for dumpingand. restoring the body B, and during the transportation of the car saidextension can be pushed in to avoid collision with objects near the sideof the track.

For locking the lever in its body-supporting position, as hereinbeforereferred to, I prefer to attach to the body a catch 0 of the form of ashort post, which passes through a slot a in the lever L near the endthereof, and is provided with an orifice above the lever, receivingthrough it a bolt I), mounted on the lever and sliding longitudinallythrough a guide-post- Z)", fastened to the lever. To the said bolt isconnected alink b, which is adapted to embrace either of the posts 0 b,and thereby confine the bolt either in its locked or unlocked position.

13 represents the gate, which is hinged to the top of the dumping sideof the body B.

For locking said gate in its closed position, I hinge to the under sideof the body the latch 0, formed with an upwardly-proj ecting shoulder,by which it engages the exterior of the bottom of the gate. To drop thesaid latch automatically with the dumping of the body B, I form thelatch with a downwardly and inwardly extending lever O, which strikesthe top of the truck during the operation of dumping the body, and thusthrows the latch out of engagement. In moving the body back to itshorizontal position the gravity of the lever 0 restores thelatch toitsnormal position to re-engage the gate as it falls into its closedposition. To cause the gate to fall more positively into said positionand also allow it to be readily removed when desired, I attach to thetop of the body the brackets I and rigidly mount thereon the U shapedbearings I, standing with their open ends facing the opposite sides ofthe body. The free ends of the said bearings are provided with verticalboltholes for the bolts Z, which confine the journals z'of the gate insaid bear-in Said journals are formed with vertical leaves j, to whichthe gate is attached.

To guard against the spreading of the top of the body B, I form each ofthe journals 1' t' with shoulders z" i, which abut against oppositesides of the bearings II. These bearings are set a sufficient distancefrom the dumping side of the body to cause the gate B to fall with itsbottom tightly against the body when the latter is turned from itsinclined or dumping position to a horizontal position.

I attach to each end of the car two bumpers F F, disposed at oppositesides of the line of draft and with a space between them, and place insaid space draw-hook G, secured to cross-bars attached to the bumpers.Said position of the draw-hook in relation to the bumpers renders theoperation of coupling the car more safe.

To guard against excessive concussion when abutting ,against anothercar, I form the bumpers F F with recesses ff in their outer ends andsecure in said recesses cushions gg of rubber or other suitablematerial.

The coupling-chain h I permanently connect to an eye in the draw-hook G.The car is thus always in condition to be coupled to another car.

hat I claim as my invention is 1. In a dumping-car, the combination,with the truck, of a body-support pivoted upon the central portion ofthe truck, a stationary support upon the truck farthest from the dumpingside of the car, the body mounted on the pivoted support and having itsdischarginggate hinged to the top of the body, and alatch for lockingsaid gate hinged to the body and provided with a lever adapted to strikethe truck and thereby unlock the gate, as set forth.

2.
